摘　　要：目的 探讨超重和肥胖患者平板运动试验与冠状动脉造影结果的关系.方法 780例患者根据体重指数（BMI）分为超重组（n=380）、肥胖组（n=160）和正常体重组（n=240）,分别行平板运动试验和冠状动脉造影检查,将其结果进行对比分析.结果 超重组、肥胖组与正常体重组的运动平板的阳性率（分别为73.68%、81.25%、32.25%）比较,差异均有显著统计学意义（P＜0.01）;超重组与肥胖组的运动平板的阳性率比较,差异无统计学意义（P＞0.05）;超重组、肥胖组与正常体重组的冠状动脉造影的阳性率（分别为70.52%、85.00%、30.00%）比较,差异均有显著统计学意义（均P＜0.01）.超重组和肥胖组平板运动试验的准确度为63.44%,敏感性为70.52%;冠状动脉造影结果的准确度为74.03%,敏感性为81.25%;两组平板运动试验和冠状动脉造影的特异性均为50.00%.平板运动试验和冠状动脉造影结果的阳性预测值分别为72.82%、84.41%,阴性预测值分别为47.17%和44.45%.结论平板运动试验是诊断超重和肥胖患者冠心病的一种操作简易、安全有效的辅助检查手段.Objective To analyze the relationship between results of treadmill exercise test （TET） and coronary angiography （CAG） in overweight and obese patients. Methods 780 cases were divided into overweight group（n=380）, obese group （n=160） and normal-weight group （n=240） based on body mass index and underwent TET and CAG. Results The positivity of TET as well as CAG was significantly higher in the overweight and obese groups than in the normal-weight group（73.68%, 81.25% vs.32.25%, and 70.52%, 85.00% vs.30.00%, respectively, all P〈0.01）. The results of TET had no significant difference between the overweight group and obese group （P 〉0.05）.The accuracy and sensitivity of TET in overweight and obese group were 63.44% and 70.52%, the accuracy and sensitivity of CAG in overweight and obese group were 74.03% and 81.25%, and the specificity of TET as well as CAG in the two groups was 50.00%. The positive predictive value of TET and CAG were 72.82% and 84.41%, and the negative predictivity value were 47.14% and 44.45%. Conclusion Treadmill exercise test is a simple, safety and effective approach to the diagnosis of coronary artery disease.
